Just wondered what sources and prices people are using for your "windows were cleaned today" slips? I've always had my own word document which I take somewhere local, I supply the paper (160gram) and then get photocopied. Less than a year ago, I was getting charged 5p per sheet, recently this went up to 12p,but went today and they now want 50p per sheet, stating they were previously charging less than cost price. I get 5 slips per sheet so 10p per slip plus the price of the paper, so say 11p per slip. How does that compare?
